While a software process is being executed, many errors and problems occur which require to reconsider previously executed process steps. In order to handle feedback in a process management system, several requirements need to be addressed: adaptability, human intervention, impact analysis, change propagation, restoration of the work context, and traceability. Feedback management in DYNAMITE meets these requirements. DYNAMITE is based on dynamic task nets and specifically supports feedback through feedback relations, task versions, and customized semantics of data flows. A methodology for feedback handling is also represented.

Software process dynamics challenge the capabilities of process-centered software engineering environments. Dynamic task nets represent evolving software processes by hierarchically organized nets of tasks which are connected by control, data, and feedback flows. Project managers operate on dynamic task nets in order to assess the current status of a project, trace its history, perform impact analysis, handle feedback, adapt the project plan to changed product structures, etc. Developers are supported through task agendas and provision of tools and documents. Chained tasks may be executed in parallel (simultaneous engineering), and cooperation is controlled through releases of document versions. Dynamic task nets are formally specified by a programmed graph rewriting system. Operations on task nets are specified declaratively by graph rewrite rules at a high level of abstraction. Furthermore, editing, analysis, and execution steps on a dynamic task net, which may be interleaved seamlessly, are described in a uniform formalism.
